Title: Waveform data processing method for logical simulation
Inventor: KOIKE MINORU
IPC: G06F11/26
Filed: 1989-09-29
Abstract: PURPOSE:To obtain the desired one of large quantity of waveform data at a high speed and to effectively use a memory by attaining a pointer structure for a signal name list and a time list. CONSTITUTION:A signal name list 1 which arrays the signal names on a memory is produced together with a time list 2 which shows the even occurring times viewed from the signals, a time list 3 which shows an event occurrence distribution viewed from the time, and a logical value list 4 which shows whether 0 or 1 is produced for each event. Thus the waveform data on the logic circuit simulation can be produced or displayed. Then those four lists 1 - 4 are connected to each other via pointers Ps, Pst', PT and Pv and the mutual relationships are defined among four lists. As a result, a large quantity of waveform data can be obtained at a high speed and at the same time the memory is effectively used.

Filed: 1990-09-25
Abstract: PURPOSE: To transmit/receive a high quality picture at the same speed as an existed system by reducing communication speed when the quality of a general exchange line is inferior and reducing erroneous transmission at the time of using the line. CONSTITUTION: When a video input/output part operates at an acquirement mode and a display mode, a bus adjusting circuit 2 realizes the access of the picture information storage memory 10 of a system control part 7 during a synchronizing signal period which is not required for the output of a screen so that a video input/output part can logically and always access to the picture information storage memory 10, and it is connected to a system bus through an address, data and a control signal. The system control part 7 accesses to the picture information storage memory 10 through the bus adjusting circuit 2 while the video input/output part gives information that the video input/output part is in the synchronizing signal period.  Thus, high quality picture information whose processing is difficult by an existed system (analog system using amplitude-phase modulation) can be transmitted/received.
